SDN: The emerging reality

Change is still afoot in Software Defined Networking, but it is now at least clear that SDN is here to stay, that SDN will be the way we build networks going forward.

Inside you'll find:

* Crossroads for OpenFlow? Once conflated with SDN, OpenFlow progress seems to have stalled. Does OpenFlow still have a significant role to play?

* Survey results: Interest in SDN is real and growing, and this survey shows where and how companies might deploy the tech.
